Listen to the dialogue and

16、decide whether the following statements are true (T) or false (F).A:On our programme this afternoon were going to be talking about a subject that has been getting a lot of attention recently and that is global warming. For years now, some scientists have been warning us about global warming. But jus

17、t how serious is the problem and what can we do to prevent the situation from getting worse? With us this morning, we have Dr. Stokes from the weather office. First of all, Dr. Stokes, what causes global warming?B:Well, basically global warming is caused by an increase in the amount of carbon dioxid

18、e in the atmosphere. Carbon dioxide is rather like a giant blanket around the earth, and it keeps the heat in the atmosphere. If the amount of CO2 in the air doubled, for example, the earths temperature would rise by about 2 degrees Centigrade, or 4 degrees Fahrenheit.A:That doesnt sound like much.B

19、:No, it doesnt. But it would be enough to melt the polar ice caps. This would raise sea levels by about 60 metres or 200 feet, which in turn would be enough to drown coastal cities like New York, Bombay and London.A:I see. That is frightening.

21、changes now, we may not be able to reverse all the damage. For example, I think that the weather in some parts of the world has been changed forever. But unless we can reduce the amount of carbon dioxide going into the atmosphere, were going to have even more serious problems.A:And how can we do tha

You will hear each sentence three times.1.Salmon are very sensitive to environmental conditions and require cool, well-oxygenated water to thrive.2.The closure of factories that

27、had poured toxins and other pollutants into the river boosted water quality significantly and modern sewage processing plants helped eliminate some of the foul smells.3.The rivers depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas

28、 starting in the 1600s.4.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.5.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotlands largest city, gained a repu

29、tation for social deprivation and rough streets.DListen to the passage and choose the best answer to each of the following questions you will hear.Running through one of Britains biggest manufacturing centers, Glasgow*, the Clyde River* was poisoned for more than a century by the fetid* byproducts o

30、f industry. The waterway bore the brunt of Glasgows economic success during the Industrial Revolution* and beyond, as pollution and chemicals destroyed its fish and wildlife populations and brewed smells whose memory still makes residents wince*. Now, with heavy industry gone and Glasgow reconceived

31、 as a center for culture and tourism, the Clyde is coming back to life.For the first time since the late 1800s, its native salmon have returned in sizable numbers, reflecting the new cleanliness of a river that was once one of Britains filthiest.The Clyde River Foundation surveyed fish populations l

32、ast autumn at 69 sites in the Clyde and its tributaries, and found salmon in seven of the nine major tributaries.The migratory fish, which vanished from the Clyde around 1880 after a long decline, first reappeared in the 1980s, but last years survey was the first to show theyve come back in healthy

33、numbers.Although commercial salmon fishing was never widespread on the Clyde, the fishs return is symbolically important for Glasgow, where salmon were once so important to the citys identity that two are pictured on its official coat of arms.The salmons comeback is also a sign of big improvements t

34、o water quality. Like sea trout, which have also reappeared in the Clyde system in recent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive.The decline of Glasgows main industries helped boost the fortunes of a river that was essentially

35、fishless for decades during the worst periods of pollution.The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators also tightened dumping rules, and modern sewage processing plants helped eliminate some of the

36、 foul* smells that once tainted* the air.With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlantic, the Clyde comeback is a rare bit of good news for Scotlands fish lovers.Since the area that

37、is now Glasgow was first settled around the year 550, the Clyde has been central to its history.The rivers depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s. Later, during the Industrial Revolution that bega

38、n in the late 1700s, Glasgow became a center of British shipbuilding and one of the countrys great manufacturing centers.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the

39、 second half of the 20th century, working-class Glasgow, Scotlands largest city, gained a reputation for social deprivation* and rough streets. More recently, its art museums and nightlife have helped drive an economic comeback that has turned the city into a popular tourist destination.Questions:1.
